Social engineering is the acquisition of information about computer systems by methods that deeply include non-technical means. While technical security of most critical systems is high, the systems remain vulnerable to attacks from social engineers. Social engineering is a technique that: (i) does not require any (advanced) technical tools, (ii) can be used by anyone, (iii) is cheap. Tradition...

This research effort focuses on improving the flexibility of production engineering for manufacturing industry by means of providing technological alternatives. A new generation of NC simulators required supporting the decision making of production engineering. In this paper a conception of NC simulator trying to fill this gap is given. This is a step forward realising Virtual

Semiconductor nanocrystals are tiny light-emitting particles on the nanometer scale. Researchers have studied these particles intensely and have developed them for broad applications in solar energy conversion, optoelectronic devices, molecular and cellular imaging, and ultrasensitive detection. A major feature of semiconductor nanocrystals is the quantum confinement effect, which leads to spat...

We argue that there is a gap between software engineering cultivated in the universities and industrial software development. We believe that it is possible to get academia and industry closer by starting projects that will require solution of non-trivial scientific tasks from one side and long-term commitment to create a product out of this research solutions from the other side. We illustrate...

A theoretical investigation is made of the dispersion characteristics of plasmons in a twodimensional periodic system of semiconductor (dielectric) cylinders embedded in a dielectric (semiconductor) background. We consider both square and hexagonal arrangements and calculate extensive band structures for plasmons using a plane-wave method within the framework of a local theory. It is found that...

The OEM’s requirements engineering and management process is affected by many residual encumbrances and future constraints. The encumbrances’ origin comes from the OEM’s strong dependency on suppliers’ software development knowledge and support. In contrast, future constraints are dealing with the assembling of software engineering knowledge, especially requirements engineering, as OEM’s core a...
